Install roller shutters afterwards. But not exterior roller shutters?

Hello, we want to have roller shutters installed afterward, but we don't know which craftsman we need to hire.
Description: The masonry consists of a 24 cm aerated concrete block and a 120 mm thermal insulation composite system with exterior plaster.
We were told that it could even be done in such a way that the box is no longer visible from the outside because it is integrated into the masonry, is that true?
Does jmg. have any expertise?

Hello,

.....We were told that you could even do it in such a way that you can't see the box from the outside anymore because it is integrated into the masonry, is that true? Does jmg. know about this?

How do you want to subsequently integrate a roller shutter box into the masonry?:confused:

Regards

When building new, you have larger openings in the masonry than the windows, so that the roller shutter box fits above the window. With your request, you would have to choose smaller windows to make room for the roller shutters!
